GOLD WASHING AND ACCUMULATIN G DEVICE.

Specification of Letters Patent.

Application filed November 15, 1917. Serial No. 202,138.

To all whom it may concern:

Be it known that we, R01 C. SAWYER and JOHN, W. WEs'r, citizens of theUnited States, residing at Pasadena, in the county of Los Angeles andState of California, have invented :a new and useful Gold Washing andAccumulating Device, of which the following is a specification.

Our invention relates to devices for collecting gold out of the beachsand or collecting gold out of sand under the washing process.

The main object of this invention is to agitate the sand whileseparating the gold from the sand when directing sand and water throughthe device.

Another object is to provide means with in the device for accumulatingthe gold while the lighter sand is passing through the device.

Another object is to provide a propelling means which draws the goldholding sand through the device.

Another object is to provide a suitable conveyer which conveys the goldholding sand through the device while agitating the sand and separatingthe gold from the sand.

Another object is to provide agitating means for washing the accumulatedgold.

. Other objects will appear from the following description and appendedclaims as well as from the accompanying drawing, in which- The figure isa longitudinal section through our device.

1 designates a casing having an intake shoe 2 expanding beyond thediameter of the device to draw the material into the device on one endwhile the other end of the device is partly closed by the overflowbafile 3, leaving an outlet opening 4 on that end of the device.Accumulating bafiles 5 and 6 are provided within the device a suitabledistance spaced from the outlet opening 4. The shaft 7 is disposedthrough the device being journaled in the bearings 8 and 9. On the end10 of the shaft 7 a propeller 11 is mounted for drawing the gold-holdingsand into the device. The screw conveyer 12 is provided on the shaft 7within the derice for transmitting and drawing the gold holding sandthrough the device. The agitating arms 13 are also provided on the shaftfor the purpose of agitating and keeping the sediment and accumulatedgold 1n that part of the device stirred up so as procure a washing and acontinuous cleaning of the sediment and accumulated gold. The overflowbafile 3 is made high enough to insure a retaining ofthe gold passingwith the sand through the device, while the accumulating bafiles 5 and 6are provided to form recesses for the gold to settle allowing thelighter sand to pass over the retarded gold in such recesses.

This device is constructed with the idea to simplify the washing of goldholding sand and is especially designed to draw wet sand through thedevice agitating the sand and at the same time allowing the gold in thesand to settle while the lighter sand with the water is caused to passthrough the device. The device can also be used below the surface ofwater as the gold can settle behind the baflles from where it may betaken when the device is raised above the water surface or by a suitabletool, as will easily be understood.

Having thus described our invention, we claim:

1. In a gold washing device of the class described a tubular body havingone fully open end and a partly closed end, the fully open end formingthe inlet for the device with an area equal to the area in the device,the partly closed end forming an oreretaining baflie and an overflowopening above the bafile within the circular area of the tubular body,and accumulating baffles within the body spaced from the ore-retainingbattle.

2. In a gold washing device of the class described a tubular body openat one end and partly closed at the other end, the partly closed endforming an ore-retaining battle and also an overflow opening above thebaflle within the area of the tubular body, and a propeller turnablydisposed at the open end of the tubular body for drawing the ore-holdingsand into and through the tubular body.
